>>1817030What pressure you can get out of a cartridge depends on the cartridge size and tire size, so figure out what size cartridge will take you from flat to something useable and get that size. Ideally get a pump that lets you turn the flow on and off so you can stop it when it gets as hard as you want it. It's meant to be an emergency repair thing so you're just trying to get home, not necessarily get your PSI on the nose. I got this one and it's bretty gud but maybe topeak ones are cheaper.
